Social Security Tax Cap: $184,500 Now, $192,300 in 2027
Social Security tax applies only to the first $184,500 of wages in 2026, and $192,300 in 2027, so high earners stop paying it mid-year. Here's how the cap shows up on a paycheck, what to do if two jobs overwithheld, and how it affects benefits.
Social Security tax applies only to the first $184,500 of wages in 2026, so anyone who earns more stops paying it partway through the year. The cap, called the taxable maximum or wage base, rises to $192,300 in 2027. Once your pay for the year passes it, the 6.2% Social Security deduction drops off your paycheck and your take-home pay goes up. Medicare tax keeps going, and earnings above the cap don't count toward your future benefit either.
How the cap works on a paycheck
Employees pay 6.2% of wages for Social Security and their employer pays another 6.2%, according to the IRS. Both stop at the wage base:
| Year | Wage base | Most an employee pays |
|---|---|---|
| 2026 | $184,500 | $11,439.00 |
| 2027 | $192,300 | $11,922.60 |
Your employer withholds until your wages for the calendar year reach the cap, then stops. Take someone earning $300,000 a year, paid twice a month at $12,500 per check. After 14 paychecks they've earned $175,000. Only $9,500 of the 15th check, in early August, is taxed for Social Security, and every check after that is $775 bigger. At $369,000 a year, exactly twice the cap, the deduction stops at the end of June.
The withholding starts again in January, when the count resets.
What doesn't stop
- Medicare tax has no cap. The 1.45% employee share applies to every dollar of wages, and employers withhold an extra 0.9% Additional Medicare Tax on wages above $200,000.
- Your future benefit stops growing at the cap too. Pay above the yearly limit isn't counted as wages for Social Security (20 CFR 404.1047), so it doesn't raise your benefit. That's why the maximum benefit goes to people who earned at or above the cap for 35 years.
Two jobs? You may have overpaid
Each employer withholds Social Security tax up to the cap on the wages it pays, without knowing what other jobs withheld. If two or more employers together took out more than the yearly maximum, the IRS lets you claim the excess as a credit on your federal tax return. Married couples filing jointly figure this separately for each spouse.
If a single employer withheld too much, the fix is different. Ask that employer to correct it. If it won't, you can request a refund on IRS Form 843 with copies of your W-2s.
The self-employed pay both halves
Self-employment tax is 12.4% for Social Security plus 2.9% for Medicare on net earnings, and it generally applies once you net $400 or more. The same cap applies, and it counts your wages first: only self-employment income that, added to your wages, stays under the cap is taxed for Social Security (20 CFR 404.1096). Someone with $150,000 in wages in 2026 pays the 12.4% on no more than $34,500 of net self-employment earnings.
Why the cap goes up
The wage base rises automatically in any year with a cost-of-living adjustment, tracking growth in the national average wage, and it never falls (20 CFR 404.1048). It was $3,600 in 1951 and $35,700 in 1983. The 2027 figure of $192,300 was published in the Federal Register on October 26, 2026, alongside the 3.6% COLA.
Raising or removing the cap is a frequent proposal for shoring up the trust fund. We cover those proposals in two bipartisan plans to fix Social Security and the push for a solvency commission.
What to do
- Check your last pay stub of the year. If you hit the cap, the Social Security line should read zero after that point.
- Add up the Social Security tax on every W-2 if you had more than one job. Anything over $11,439 for 2026 is a credit on your return.
- Plan around the 2027 change. High earners will see the deduction last a little longer next year. See what else changes on our cheat sheet, and estimate your benefit with our benefits calculator.

Frequently asked questions
- What is the Social Security tax cap for 2026 and 2027?
- The cap, also called the wage base or taxable maximum, is $184,500 for 2026 and $192,300 for 2027. Employees pay 6.2% of wages up to the cap, so the most an employee pays is $11,439 in 2026 and $11,922.60 in 2027.
- Why did my paycheck go up near the end of the year?
- If your wages for the year passed the Social Security wage base, your employer stopped withholding the 6.2% Social Security tax. Withholding starts again with your first paycheck in January.
- I had two jobs. Did I overpay Social Security tax?
- Possibly. Each employer withholds up to the cap on its own wages. If the total withheld by two or more employers is more than the yearly maximum, you can claim the excess as a credit on your federal tax return. If one employer alone withheld too much, ask it to fix the error or file IRS Form 843.
- Does the cap apply to Medicare tax?
- No. The 1.45% Medicare tax applies to all wages, and employers withhold an extra 0.9% Additional Medicare Tax on wages above $200,000.
- Do earnings above the cap raise my Social Security benefit?
- No. Pay above the yearly cap isn't counted as wages for Social Security, so it doesn't add to your benefit. That's why the maximum benefit goes to people who earned at or above the cap for 35 years.
